    does the van dykes crystals have a anti microbial agent in them like the bucktan or arrow head crystals for auto tanners have? if not is there any anti bacterial stuff I can add to it that is safe? also can I just pickle the skins in the auto tanner with van dykes crystals and then brush on McKenzie tan afterwards and let sit over night or can I add McKenzie tan to the auto tanner. thanks!

    The main ingredient in most of those crystals is alum. With alum, you shouldn't need a bactericide. As soon as alum hits water, it makes a small amount of sulfuric acid. That's why the pH is so low. Around 3. Long story short, a bactericide is wasted, and is overkill.
    If the Mackenzie Tan utilizes a synthetic tannage, which I assume it does, that would be a great combination tannage.(brushing on) You have to neutralize first. Without getting into a long explanation, adding this type of tan straight to the drum won't work well at all.
